Your application is supposed to work with any PSGI servers without any code modifications, but if your application uses $c->res->write to do streaming write, this engine will buffer the ouput until your app finishes.

To do real streaming with this engine, you should implement an IO::Handle-like object that responds to getline method that returns chunk or undef when done, and set that object to $c->res->body.

Alternatively, it is possible to set the body to a code reference, which will be used to stream content as documented in the PSGI spec.

When your application runs behind the frontend proxy like nginx or lighttpd, this Catalyst engine doesn't automatically recognize the incoming headers like X-Forwarded-For, because respecting these headers by default causes a potential security issue.
